CVE-2022-50824 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak In check_acpi_tpm2(), we get the TPM2 table just to make sure the table is there, not used after the init, so the acpi_put_table() should be added to release the ACPI memory.
A memory leak vulnerability has been identified in the Linux kernel's TPM driver, specifically within the TPM2 ACPI table handling. The issue arises in the 'check_acpi_tpm2()' function of the 'tpm_tis' driver, where the ACPI TPM2 table is retrieved but not properly released after use. This oversight can lead to unnecessary memory consumption. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to the latest version where this issue has been addressed.
